Question

Assertion: True solution is a homogeneous mixture of two or more substances in which the particle size of the material dissolved (solute) in the solvent is less than ${10}^{-9}\text{m}$ or $1\text{nm}$.
Reason: It can scatter the beam of light passing through it.

• A. Both assertion and reason are correct and reason is the correct explanation for assertion.
• B. Both assertion and reason are correct but reason is not the correct explanation for assertion.
• C. Assertion is correct but reason is incorrect.
• D. Both the assertion and reason are incorrect.

Answer 1

The correct option is C Assertion is correct but reason is incorrect.

True solution is a homogeneous mixture of two or more substances in which the particle size of the material dissolved (solute) in the solvent is less than ${10}^{-9}\text{m}$ or 1nm. As the size of particles is small, they do not scatter a beam of light. So, the path of light is not visible
